AXLE-BEARING.

Application filed July 14, 1911.

Be it known that 1, JOHN KIN-c, a subject of the King of Great Britainand Treland, residing at Leeds, in the county of York, England, haveinvented certain new and useful Improvements in Axle-Bearings SpeciallyApplicable for Corves and Similar Mine-lVagons; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will en able others skilled in the art to which itappertains to make and use the same.

This invention relates to axle bearings and is intended moreparticularly for use with corves and similar mine wagons.

The object of the invention is to enable the axle to be readily removedand replaced, to reduce the friction, to provide a simple, eflicient andinexpensive form of bearing, opposing no obstacle to the ordinarylubrication from below.

The invention is hereunder described with reference to the accompanyingdrawings; Figure 1 being a vertical section on line A A of Figs. 2 and3. Figs. 2 and 3 are both plans, the former looking down onthe top, andthe latter looking upward at the underside of the bearing.

The bearing is made in two parts, which for the sake of distinction maybe respec tively termed, the pedestal, lettered a 7) in the drawings,and the loose cheek. lettered c (f.

The pedestal consists of a base plate a and a. side cheek Z), hereintermed the fixed side cheek, cast in one piece with the base, so as tobe integral therewith, and situated to one side of the center linethrough the base at. These side cheeks are normally in contact with theshaft on opposite sides thereof near the horizontal plane of its axialline.

According to this invention, the opposite side of the base has a sliderecess formed on its under side, the sides of the slide which areinclined, are indicated by the letter 6.

5' This slide runs parallel to the axle The base (Z of the loose sidecheek, hereinafter termed the sliding piece (Z, is formed to fit andslide in the slide 6 e, the sides of the sliding piece being beveled orinclined at the same angle as the sides of the recess or slide 6 e.

The base of the pedestal is provided with two bolt holes 9, throughwhich the bolts securing it to the main longitudinal bars or bearers ofthe corf or wagon are passed. The sliding piece d is also provided witha Specification of Letters Patent.

bolt hole 9; which when the sliding piece is fitted in the slide recess6 c, is coincident with the bolt hole in the same side of the base a, sothat the same bolt serves both to secure this side of the base a to thewagon or corf, and the loose cheek in position in the slide 0 c, andprevents any movement of the loose cheek about the bolt. The lower endsof the two cheeks, i. e. at 17L, are made preferably level with thecenter of the axle for the greater part of their length; but at one end,viz: at 2' they extend still lower by a distance roughly equal to halfthe radius of the axle. These extensions 2' are for the purpose ofpreventing the axle dropping out of its place, when the corf or wagon islifted. Less frequently both side cheeks may be nade to terminateslightly below the level of the center of the axle. The bearing, beingopen below the axle, will permit free lubrication thereof from below andthe lubricant has better access to the side of the axle becauseprojections 2' are at one end of the cheeks only and cover little of theaxle surface. It will be evident, that in order to disconnect the axle,it is only necessary to loosen the bolt connection at g, when the loosecheek can be drawn out sidewise.

Bearings consisting of a base plate having a fixed side cheek integraltherewith, and a loose side cheek with the base fitting in a slideformed in the base plate at right angles to the axle, or merely restingon this half of the base plate are not new, and no general claim is madeto such. These have the disadvantage, that the loose side cheek ismerely supported by the holding bolt and can rock about the same, andthat with the former it is impossible to withdraw the loose cheeksidewise, which is usually much more convenient than to withdraw itendwise.

To reduce the friction and the amount of lubrication required, and wherethe additional expense is not prohibitive, the bearing is fitted withone or more antifriction rollers. As illustrated, the bearing isprovided with two antifriction rollers a, mounted on pins is, fitted inrecesses formed for them in the two side checks. The circumferences ofthe rollers a project just within the curved inner faces of the two sidecheeks, so as to take the thrust between the axle and the bearing. Therecess for the rollers is carried through the cheeks so as to emerge atthe top as shown at m, or they may curve outward to the outside faces ofthe cheeks near their junction with their bases. In some cases, it ispreferred to have only one anti-friction roller support, which is fittedvertically above the center of the axle.

No general claim is made to the use of friction. rollers in mine axlebearings.

Having thus described my invention,what I claim and desire to secure byLetters Patent is 1. An axle-bearing pedestal having a fixed side-cheekand provided with a guideway parallel to the axle, in combination with aremovable side cheek fitted in said guide-way, these side cheeks beingprovided at one end with a pair of downward extensions.

I 2. An axle-bearing pedestal having a fixed side-cheek and providedwith a guideway longitudinal of the bearing, in combi nation with asidecheek removable longitudinally in either direction fitted into saidguideway and means for fastening the same, the two guide-cheeks formingan axle-receiving recess and extending approximately to the middle linethereof.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
